Vim jump between words and stop at end of line

Question

In normal mode, b and w are jumping between words,

and I would like to stop at the end of line.

For example:

The cursor is right over here

When I press w, what I expect is

Instead, the cursor jump to beginning of next line.

Should I set iskeyword or something? Thanks.

Answer 1

Use e key - it moves cursor to the end of a word-object. See :h word-motions for more movement keys.

Answer 2

While I deeply agree with @grodzik comment (it's better to learn how to use motions as they are, because later you will forget that you have custom motion mapping) here is a custom funciton and mapping to do what you want:

" Override w motion
function! MyWMotion()
    " Save the initial position
    let initialLine=line('.')

    " Execute the builtin word motion and get the new position
    normal! w
    let newLine=line('.')

    " If the line as changed go back to the previous line
    if initialLine != newLine
        normal k$
    endif
endfunction

" Override b motion
function! MyBMotion()
    " Save the initial position
    let initialLine=line('.')

    " Execute the builtin word motion and get the new position
    normal! b
    let newLine=line('.')

    " If the line as changed go back to the previous line
    if initialLine != newLine
        normal j^
    endif
endfunction

nnoremap <silent> w :call MyWMotion()<CR>
nnoremap <silent> b :call MyBMotion()<CR>

I haven't tested it extensively so maybe some corner cases will create problems but that should be a good start.

Also as I mentioned before this code is only to show that it is possible to do that I wouldn't recommend to use it.
